. Application filed November 15, 1897. Serial No. 658,563. (No model.)

To (oZZ whom it may concern.-

Be it known that I, JosEPH SHACKLETON, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements inSmoke-Oonsumers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw-' ings, and to the letters of reference marked thereon, which form a part of this specification.'

This invention relates to improvements in smoke-consumers.

The object of the invention is to provide means for effectually destroying or consuming black smoke that comes from the combustion of coal, oil, and other fuel. The means consists of two mediums, through which the smoke is consumed, first, by providing a superheated iron wall and upper brick wall, against which the said smoke impinges and which destroys a greater portion of said substance, and, secondly, a flame in the rear of and above said first medium, which destroys the remaining small portion of said smoke. The mediums consist of a castiron oven or air-superheater placed in the rear of the fire on top of the hollow bridge-wall, into which air is admitted, a wall of brick slabs placed on said oven, and a manifold burner for burning vapor that is generated from hydrocarbon oil, the said burner ejecting a continuous and solid flame or wall of flame in the rear of and above the oven and upper brick wall, all constructed and arranged in a 'manner hereinafter more fully described.

In the accompanying drawings, Figure 1 is a side elevation of a furnace and boiler, showing my appliances on the line 00 a: of Fig. 2. Fig. 2 is an end elevation of the same, showing the bridge-wall and-oven.

Similar letters of reference indicate the same parts in both views.

The bridge-wallA is constructed in the rear of the fire-box 13, with its upper surface lying on a plane with the fire-grate O. The said bridge-wall is provided throughout its length with an upper air-chamber a, with which an air-pipe D communicates, the said pipe being supported in the rear wall E and in the bridgewall. I) designates a metallic plate placed on the topof the bridge-wall and upon which the spreading sides 0 of the cast-iron oven are supported. This oven terminates upwardly in a ceiling c and two verticallyextending flanges 0, running longitudinally of said oven. These flanges a provide an intervening recess into which a brick wall is placed. This wall consists of brick slabs cl, the upper edges of which have a semicircular curve coinciding with the shape of the boiler. Between this Wall and the lower surface of the boiler there is a space f, through which any smoke remaining after the impingement with the hot wall of the oven and the upper brick wall will pass and become consumed by a wall of flame in the rear of the said space f. The bottom plate of the oven has a series of air ports 6 throughout its length communicating with the air-'chamber in the bridge-wall.

h designates a burner-pipe placed in the oven on one side of the row of airports c. This burner-pipe has a series of jets or short pipes 2', that project into a line of orifices in therear wall of the oven and which send a solid and continuous wall of flame upward, completely closing the rear of the space f. The gas is generated from hydrocarbon oil that is fed through a pipe is and is converted into gas in a retort it, placed against the bridge-wall A. The gas enters an injector n, into which steam is passed from the boiler through a pipe 7c and is injected with the gas into the burner. The steam, air, and gas, mixing and becoming superheated, meet the products of combustion of the burning fuel in the rear of the oven and effectually destroy any smoke that remains in the product.

Having described my invention, I 'claim-- In a smoke-consumer, the combination of a bridge-wall having an air-chamber therein opening through the upper longitudinal sur= face thereof, an air-pipe communicating with the rear side of said chamber, an oven mountabove the fire-slabs, substantially as and for ed on said bridge-wail, the said oven having the purposes specified. 10 a longitudinal row of orifices in its rear side, In testimony whereof I aifix my signature and a longitudinal recess in its upper side, a in presence of two Witnesses.

5 Wall of fire-slabs mounted in said recess, and JOSEPH SHACKLETON.

a hydrocarbon-burner inclosed in said oven WVitnesses: and adapted to eject a wall of fialne through MICHAEL LOUOKs, the rear side of the oven, and across the space R. J. MCOARTY.
